T 0 all whom' t may concern Be it known that I, JOHN IV. VINCENT, acitizen ofthe United States, residing at Kansas City, in the county ofIacksonand State of Missouri, have invented certainnew andusefulImprovements in VVeather-Strip- Forming Machines; and I` do declare thefollowing to be a full, clear, and exact description of theinvention,isueh as will en able Others skilled in the art to which itappertains to make and use the same, refer encebeing had to theaccompanying drawings, and to the lettersand figures ofreference markedthereon, which form a part of thisspeci'fication.

This invention relates to a sheet metal working machine and particularlyto means for cutting and crimping sheet metal in the form of weatherstrips in whichthe sheet is formed with a crimped rib or abutment atright angles to the plane of the sheet.

The invention consists in providing certain novel parts and combinationsof parts, all of which will be specifically referred to hereinafter,reference being had to the accompanying drawings, in whichi F ig. VI isa perspective view of a machine constructed in accordance with myinvention,part` of the feedtable yand sheet being broken away to showcertain operating mechanismV therebeneath, and part of the crimpingroller-housing being broken away to show the operating mechanism for thecrimping rollers.

Fig. II is a cross sectional view on the line II-II of Fig. I.

Fig. III! is an enlarged elevational lview of a pair of the rib-formingrollers.

' Fig. IV yis a similar 'view of a pair of the rib-,crimping rollers. f

Fig. V is an elevational view of the sheet feed roller operatingmechanism.

F ig. VI is a detail view of the finished weather strip, the product ofthe machine, and 1 Fig. VII is a top plan view of a rmachine constructedin accordance with my invention.

, In the illustrated embodiment of the invention I have shown a frameconsisting of a table 1 vsupported upon standards or legs 23, 4 and-5.Projecting upwardly from the table -1 arev slotted standards 6 and 7, inwhich is a vertically movable reciprocatory knife, 4resting upon theexpansion Speecatonof Letters Patent.

springs 9.and 10 Aand engaged by the upper ends lof the` pitmen 11 andl2, which are connected to the cranks 13 and 14 on the rock shaft 15,mountedy in bearings inthe standards or legs `3 and 5. f

The rock shaft 15 is provided with a crank arm 16,y projecting` inwardlytoplie in the path yof the roller Vor projection 17 on the rotating disk18, rigid on the shaft 19` in ybearings l2() and 2l. Thel shaft. 19 isrotated by a sprocket chain which passes around a sprocket 22kon shaft19 and around a sprocket 23 on shaft 24, in bearings 25 and 26,,supported from, the standard .3 and table 1 respectively (see Fig. I).I

The shaft 24 carries a pulley 27 driven by a belt 28 from the motor 29on the bracket 30, carried `by the machine frame. Therefore-,when themotor is operating, the shaft 19 will be rotated, causing the roller orprojection 17 to intermittently contact with the crank arm 16 to operatetheV knife 8 against the action of the springs 9 and 10 and after theroller or projection 17 has moved Ofl" the crank arm 16, the springswill raise the knife 8 and, through the medium ofzthepitmenjll and 12,the shaft 15 will be rocked so as tov raise `the arm 16 lin a positionvto again be actuated by` the .projection or roller 17, when it reachescontacting position during each cycle of its operation. e

Means is provided fork feeding `the sheet across thetable so thattheknife mayshear it. The means illustrated consists of an idler roller31, co-operating with a positively driven roller receiving itsmotionfrom a pulley 33 onV shaft32. The pulley is driven through thevvmedium of a belt 34, passing around the pulley 35 on shaft24 and it isadapted to rotate `the roller 36 to feed the sheet37 toward the knife.When the knife has severed'thev sheet, it will drop `into thetrough-shaped guide 39 and be engagedby the rollers 42 and 43. Sincekthe distance between the rollers 42 and 43 is slightly less than thewidth` of the severed strip.v the `strip will cup slightly and itsedgeswill spring into the grooves 40 and 41 in the rollers 42 and 43 so thatthe rollers will vguide and deliver it tothe forming rolls.` 'Ihe roller42 is driven from a shaft 44, having a `gear 45 meshing with a gear 46on shaft 24, so that the edges of the severed sheet will be frictionallyengaged by the floors of the grooves 40 and 41 and be fed to the rib- Vapositively forming rollers, there being threesets of,

rollersillustrated. in the drawings, said, sets bearings 59 and Y whenvthe shaft 24 rotates, the shaft 63 will medium ofthe gears,

rotatev and through the 48 and 49 Vor ribwillfdriye the `sets' 4T,forming rollers.

IIn'actlualf practice the ribs and grooves of the respective 'sets willbe progressively di- 'Ininishech` thatfis, there will befafrelativelywiderib and a relatively wide groove forv the iirst'set47, and-arelatively thin groove and La correspondingly thin flangel 561f`0r thesucceeding setsof-rollers sothat the sheet or strip willbe first formedinto shape to provide' thel rib 66 for the strip 67` with the groove68`relatively wide, but as 'the rib 66 progresses vthrough therespective sets of formingf rollers 47,' 48 and" 49the sides of theyribsV will be drawn grooves'fwill beV relatively narrow. Furtherprogression ofthe sheet 67 will move the rib between the crimpingVrollers in thehousing 69 so that the sides of the rib` 66 willbe crimpedtogether with the' inner ,sides off the tactto afford a slightspring'or'give to the rib 66.7 Y

'llhecrimpingrollers are shown as consisting of two pairs, one paircomprising. a flanged idler roller` 7 2 mounted in bearings thehu'sing69 and a positivelywdriven flanged roller 73, 'also mounted inbearings inthe housing on a shaft v74, the shaft 74 carrying gear751meshin'g with an `intermediate gearv 7 6, which in turn meshes Vwitha gear 717 on the shaftV TSFOf-the flanged roller 79of the second set,theflanged rollerv 79 having-'a complementaryidlerroller 80, alsomounted vinV they housing- 69 and correspondiiig'to; the rollersf72.The' gears 75 and 77 receive their motion from thesgear 76, whichifsldriven by a gear V81 on thefshaft63. The housiiig69 is provided witha slot 82 through which the finished strip may pass onto the table83. f

The roller 86 is not continuously driven but' its shaft 36 ycarries aratchet 84 adapted tobe lintermittentlyl engagedA by a pawl 8 5 on thelever86, normally retracted by the spring 87, there,'also being aspring88 betwgeenthe` lever and the pawl. The lever 86fentends radiallyfrom the shaft', on

circumferential rib or flange 56 oftogether until the Y portions andV71V not quite in intimate con.

Y nism,

which it is loosely mounted so that the pro-V jectionlv 89 on, thepulley 32 A may intermittently contact with.V it and rotate the shaft 36a suiicient distance to allow the sheet to feedfone width ofthe strip tobe formed into 70 vthe finished product during each cycle of operationso that the sheet 'is intermittently fed to the groove l39 as it istraversed longitudinally of the machine and while the feeding stepistruly intermittent, theA operation is substantially continuous for asfast-as the sheet is cutinto strips, it isfedinto the forming andcrimping rollers'l to make the finished" product.

The feedv operating mechanism shown. in Figz`V'will rotate vthe drivenroller 36. to feed the sheet 87 a certain `distance intothe machine,the. extent ofthe feed determining the width ofthe weather strip to beformed; Different widths ofweather strips may ybe made by changing thefeed mechanism to govern the extent of movement ofthe sheet, as will'bewellunderstood.V

From the foregoing it will be seenthatas the sheet is fed Vbetween therollers 31L and- 86itl willbe cut, then fed longitudinally to theforming rollers andV froml the forming rollers to the crimping rollers,makingthe weather strip in the form shown in Fig. VI but with the sides*mand 7l practicallyv intimate contact. v
